WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 329,355, dated October 27,1885.

Application lcd June 25, 1885.

To all whom, t may concern:

Be it known that I, ALBERT J. Barns, a

citizen of the United States of America, residf ing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Vire-Barbing Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a plan view of the machine on the top. Fig. 2 is a cross-sectional view of the machine on line 2 of Fig. 1, looking in the direction from which the strand-wires enter the machine, to more clearly show the oscillating cutter-heads for holding the barb-cutters. Fig. 3 is a detail view of the barb-cutters as they appear when making the first cut to form the first two prods of the barb, it being a face view of the ascending cutter and a plan view of the stationary cutter and a cross-sectional view of the two descending cutters, all located as shown in Fig. 2. Fig. 4L is a side view of the machine, looking in the direction from the side to which the twister attaches and from which the strand-wires emerge, showing the mechanism for oscillating the cutter-heads. Fig. 5 is a detail view of the cutters as they appear when they are severing the barb from the barb-strip and forming the two last prods of the barb, it being a face view of the descending cutters, a plan view of the stationary cutter, which also serves as a barb bender, and a cross-sectional view of the descending cutter, it being the reverse position of the cutter-heads and cutters as shown in Fig. 2. Fig. 6 is a detail view showing the cutters as they appear when severing the barb from the barb-strip to form the two last prods of the barb, it being a side view of Fig. 5, showing a face view of the stationary cutter and a side view of both the ascending and descending cutters. Fig. 7 is a side view of the paw1- and-ratchet mechanism on the feed-roll shaft, to intermittingly rotate the feed-rolls and feed in the barb-strip. Fig. S is a perspective view of the barb-strip as it appears when the two first prods of the barb are cut and formed. Fig. 9 is a perspective view of the guide that guides the two strand-wires into the machine between the cutters in position so the barbstrip may be fed in between them. Fig. 10 is Serial No.169,726. (No model.)

a perspective view of a iinished barb as it would appear detached from the strand-wires; and Fig. 11 is a side view of a barb and a cross-sectionv of the strand-wires, showing the barb seated between them, it being the iinished product of the machine.

This invention relates to certain improve.

ments in a wire-barbing machine for automatically cutting and forming four-pointed iiat metal barbs and setting them between a pair of strand-wires, to be held therein by means of the cabling together of said Wires, which improvements are fully set forth and described in the following specication and claims.

Referring to the drawings, Arcprescnts the main frame or bed of the machine, and is intended to be supported on suitable legs or foundation, and supports the working parts of the machine.

S and S are a pair of parallel rock-shafts mounted on said bed in their respective boxes B and B2. These boxes are held in position on the top of said bed by means of cap-screws (shown in Fig. l) passing through the slots in the base of said boxes, so they may be set to or from each other by means of the set-screws b and b2, for the purpose of adjusting the barb-cutters. The outer ends of the shafts S S are respectively provided with the arms E FX, rigidly secured thereto, as shown in Fig. 4. These arms are connected by means of the sliding bar D through the medium of rollerwrists attached to its side, and that traverse the slots F F of said arms. A pitman, C, connects said sliding bar D with wheel B by means of the wrist-pins d d. The slide is supported at one end in a box, I, and at the opposite end by means of the shaft H, which passes through slot H in said bar. Power to drive the machine may be imparted to said wheel, which, when it-rotates, will reciprocate sliding bar D and rock the shaftsS S through the medium of pitman c and arms E E. To the opposite end of said shafts are rigidly secured hubs, to which are attached the oscillating cutter-heads a, a', a2, and as, as shown in Fig. 2. The cutters I?, P, P, P2, and I)3 are each respectively held in said cutter-heads by means of proper cap-plates and cap-screws fortheirproperadjustment. Thecutterheads on each shaft are set so they stand at right angles with each other, and are arranged so that when they are oscillated they will alter! natelyface and meet each other to cut and form the barbs. Cutter-head ct has secured in it the two cutters P and P, and cutter-head a3 has secured in it the cutter P. These cutters, in conjunction with the stationary cutter R, secured to the top of the bed A by a cap-plate and capscrews, as shown in Fig. l, cut and form the rst two prodsof the barb and leaveit in the formshown in Fig. 8. The barb is formed from a thin strip of tlat metal, b. The cutter-head a has secured, in it 'the cutter P2, and cutter-head ct2 has secured in it u the cutter P3, and when the cutter-heads are the said cutters P2 and P3 will meet, as shown in Fig. 6, and sever the barb loose from the barb-strip on a line shown by the dotted lines in Fig. 8, and bend the prods and form the barb, as shown in Figs. 6, 10, and 11.

R represents the upper roll of apair of feedrolls,between and by means of which the barbstrip is fed into the machine intermittingly and in a diagonal direction along on the top of bed A, under a guide-plate, y', so it will enter between a pair of strandwires, w, and over the stationary cutter R, as shown in Figs. l, 2, 3, 5, and 6, and between the oscillating cutters, so that a diamondshaped barb may be cut from the end of the barb-strip and waste no material. rlhe feed-rolls R are rotated forward intermittingly to feed in the barb-strip by means of the pawl-and-ratchet device shown at T, T, y, and z, Figs. land 7. This ratchet mechanism is connected by means of the pitman z to a crank-pin on the cranlz-wheelVon the rear end of shaft H, and when the said shaft rotates said mechanism will be operated to feed the barb-strip forward intermittingly far enough each time to form av barb. The upper face of bedA is provided with a guide-block, J, (shown in Figs. 1, 2, 3, 5, and 9,) secured thereto by means of a cap-plate and cap-screws, as shown in Fig. 1. The strand-wires w enter the machine from one side, the upper wire lying in the channel r, and the lower one in channel r', ofsaid guide. The inner end of said guide stands in, relation to the cutters as shown in Figs. l, 2, 3, and 6, and holds the said wires firmly, one immediately above the other, and far enough apart, as shown in Figs. 2 and 6, so the barbstrip b can be fed in between them. The strandwires are intended to be taken up and cabled by means of an ordinary twister and spooler, not necessary to be shown, as it forms no part of this invention. However, the throat of the twister having on itthe pinion K, is shown .in Fig. l to locate it and show the strandwires entering it.

The operation of the machine is substantially as follows: The strand-wires w 'w are first threaded through the machine oft their respective reels through their respective guide-channels r r of guide-block J to a spool in the twister. The barb-strip b, having its end cut oft' in a diagonal manner in the form shown in Fig. 3, is then passed into the machine between the feed-rolls R until its pointed end has passed in between the strandwires far enough so they will stand over the center of the barb to be formed, the point of the barb-strip lying on the upper face of stationary cutter R, as shown in Figs. l, 2, and 3. rlhe barb-strip bis then in position for the oscillating cutters P P P to cut and form the iirst two prods of the barb and leave them in the form shown in Figs. 2 and 8. The partial rotation of the shafts S S by the means hereinbefore described will oscillate or move the cutter-heads av and a3, with their respective cutters, toward each other. The form 0;" slot F in arm E on shaft S, to whch cutter-head al is attached, is such that the face of its cutter P will be moved to stand on the same plane with the upper face of stationary cutter R, as shown in Fig. 2, and hold it stationary until cutter-head a descends with its cutters P and P, and, in conjunction with cutter P and stationary cutter R,shear the two first prods of the barb and bend them down to the position shown in Figs. 2 and '8.

Fig. 3 is designed to show the relative position of the cutters with relation to each other and the position of the barb-strip at the instant the operation of cutting and forming the first two prods of the barb. The cutters P and P have their cutting-faces so formed that they will, in conjunction with cutters P and R, begin to cut at the points of the barbprods rst, and as they descend bendthe two first-formed prods downward, as shown in Figs. 2, 5, 6, 8, l0, and l1, so they stand at about right angles with each other. Gutterhead a3 is provided on its face with a small bender-port, fm, (shown in Figs. 2 and 3,) set a little forward of cutter P and a littleat one side, and attached to said head in the same manner as said cutter serves to support the central part of the barb while the operation of cutting and forming the two'tirst prods is being performed. The barb-strip and partially-formed barb remain stationary and in position as left by the said cutters until.- the cutter-heads c a2 have been oscillated toward IIO each other by means of the reverse movement of arms E E and slide D, and their cutters P2 and P3 close upon the barb to sever it loose from the barbstrip and form the two remaining barbs, as shown in Figs. 5, 6, and 10. The form of slot F in'arm E is such that the slide D will move cutter P2 to a position so its upper face will be on the same plane as the upper face of stationary cutter R, as shown in Fig. 6, and stand in that position until cutter P3 moves farther down and, in conjunction with cutter P2, severs the barb loose from the strip b, as shown in Fig. 6. The cutter P3 is formed on its cutting-face, as shown in Fig. 6, so it begins to cut at the base of the prod, and in its descent carries the body of the barb down with it, and by means of the point of its fellow prod, resting on the upper face of stationary cutter R, the body of the barb is bent, as shown in said figure, so these two last-formed prods will stand at a right angle from each other, and when severed entirelyloose from the barb-strip is left in the form shown in Figs. 10 and 1l. In order to permit the bending of said two last prods, as stated, the lower strandwire must of necessity be sprung downward a little distance, which spring is permitted by the depth of the guide-channel rof guide-block J.

Figs. 5 and 6 are designed to show the relative position of the cutters with relation to each other when the operation of cutting and forming the two last prods is being performed. When the cutters P2 P3 separate, the strandwires will immediately close on the newlyformed barb, so it may be held between them by means of their being cabled together by the twister, and is carried along out of the Way of the next succeeding barb as the strands are being spooled by the twister and spocler. The strandwires pass continuously through the machine, but their frictional contact with the barb is not sufficient to interfere with its formation, or carry it along out of the machine until it is severed loose from the barb -strip, as stated. The portion of the cutting-face of cutter P3, that cuts off the eXtreme point of the last-formed barb, is square, so the metal at and near the point of the barb may all be out at once, to prevent breaking or bending of the barb-point.

The machine is timed so that the instant the barb is severed loose from the barb-strip, and begins to pass on out of the machine by being cabled with the strand-wires, the feed mechanism will feed forward the barb-strip far enough for the next succeeding barb, when another like operation cuts, forms, and sets the next succeeding barb.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is as follows, to wit:

l. In a wire-barbing machine, the combination of the oscillating cutter-heads a a a2 a, having the cutters P P P P2 P3, stationary cutter R, strand-wire guide J, having the guide-channels r i", shafts S S', arms E E', having respectively the slots F F', slide D, having roller-wrists to traverse said slots, pitman C, drive-wheel B, and the barb-strip mechanism, all adapted to operate substantially as and for the purpose set forth.
